Growing macadamia in a pot
Compost and drainage
Macadamia needs sharp drainage, so this matters more in a pot than in the ground. Use a free-draining mix (add perlite, grit or bark to standard compost), always pick a container with drainage holes, and never let it stand in a saucer of water.
Watering macadamia in a pot
Containers dry far faster than open ground, so macadamia in a pot needs checking more often than the general guidance of "Keep evenly moist; deep water weekly in dry spells, more during flowering and nut fill" — especially in summer, wind, or a heated room. Check the top few centimetres with a finger rather than watering on a fixed day.
Potting on
Pot on when roots show through the drainage holes or growth slows noticeably — usually every 1-2 years for a plant this size. Move up one pot size only; jumping several sizes leaves wet compost the roots cannot reach, and that is what rots them.

Growing macadamia in containers — FAQ
Can you grow macadamia in a pot?
Macadamia can be grown in a container while young, but it reaches about 15 m, so a pot is a medium-term home rather than a permanent one. Start it in a 40-60 cm (16-24 in) across planter, expect to pot on as it grows, and accept that container life will keep it smaller than it would be in open ground — which is often exactly what people want.
